Replacing iqoo 11 battery

[chloroformaa]

Hi..I currently own a vivo iqoo 11 5g phone ..been using it for.last one year, super fast phone and very fast charging (comes with 120W charger)...but now , battery is underperforming..battery score is 47 percent in accu battery...so want to replace it....I checked that it is mentioned on battery, the capacity as 5000 mah and watt around 20W..the main thing I want to ask is, that when replacing battery , how do I take into account superfastcharging ..?..I had thought battery would also mentioned 120 W since charger mentions that but that isn't the case..so how do I ensure that replaced battery will also support supercharging..?..(0 to 100 in 15 min with the associated 120W charger)..is the supercharging characterisitic of phone and not the battery..?...or I just ensure that I get similar specs battery as previous and when I put into the same phone, super charging will automatically be there..?..
I mean, there are many phones which have 5000 mah battery, so i don't want that after replacing battery, my phone stops the supercharging and charges like normal..how do I differentiate that..?
Also are there vivo authorised service centres here in south africa..?

fast charging is something I avoid and only use it when desperate. That's probably why your battery is stuffed
